HTTPS is supported by default in the FA model. To support HTTP, add **network** to the **config.json** file and set the **cleartextTraffic** attribute to **true**.
```js
varconfig={
"deviceConfig":{
"default":{
"network":{
"cleartextTraffic":true
}
//...
}
}
}
```
The **cleartextTraffic** attribute is not involved during application development in the stage model.
The download server must support the HTTP HEAD method so that the size of the data to download can be obtained through **Content-length**. Otherwise, the download task fails. If this is the case, you can check the failure cause through [on('fail')<sup>7+</sup>](#onfail7).

Only HTTP requests are supported. HTTPS requests are not supported.
